To me, going into discretion to get home is preferable than to have another crew repo down route to fly the sector home while you ride in the back. As is going into discretion to avoid an overnight (somtimes).
Be careful what you ask for as you just might get it: Twice the pairings for the same amount of duty time. I'm sure nobody wants to DOUBLE their number of monthly duty days just to prove a rather minor point.
Maybe that's just me.
